Hasil Adkins (pronounced "Hassle," not "Haysil") (April 29, 1937 - April 25, 2005), was an Appalachian country, rock and roll, and blues musician, though he was frequently considered rockabilly and sometimes primitive jazz. He generally performed as a one-man band, playing guitar and drums at the same time and singing. Hasil was equally skilled on the harmonica and on keyboard.
